Figure 21 - IN3/IN4 NPN Input Command using Scanner Power

Input devices can be supplied by either scanner power (VS and GND) or external power

supplies (Vext).

Electrical isolation between the input command logic and the scanner is maintained when

powering the input devices from an external supply voltage (Vext).

The driving logic of the input signals may be powered, for convenience, with the voltage

supply between pins 9 (VS) and 23 (GND) of the 25-pin or 26-pin I/O connector. In this case,

however, the device is no longer electrically isolated.

The voltage available on the 25-pin or 26-pin I/O connector, is physically the same as used

to power the scanner.

The electrical features of these inputs are:

Maximum voltage 30 V

Maximum current 10 mA

Outputs

Three general purpose outputs are available.

Pin Name Function

8 OUT 1+ Configurable digital output 1 – positive pin

22 OUT 1- Configurable digital output 1 – negative pin

11 OUT 2+ Configurable digital output 2 – positive pin

12 OUT 2- Configurable digital output 2 – negative pin

16 OUT 3A Configurable digital output 3 – polarity insensitive

17 OUT 3B Configurable digital output 3 – polarity insensitive

The function of the three outputs OUT1, OUT2 and OUT3 can be defined by the user.
